High tibial osteotomy (HTO) surgery

Osteotomy ("bone cutting") is a procedure in which a surgeon removes a wedge of bone near a damaged joint.In particular, is removed bone from the outer side of the large lower leg bone (tibia) near the knee. After removing the bone wedge, the surgeon will bring together the remaining bones and secure them, most often with either pins or staples. Surgeons often do an osteotomy to correct certain knee deformities such as bowleg (varus) and knock-knee (valgus) deformities of the knees. Nowadays, the actual necessity of osteotomy, beside as a prophylactic operation, is still debated.
